Fun, isn't it? Arguments about what's 'right' and what's 'wrong' in English can go on forever, because there is no central authority.

There's lots of things that can seem perfectly natural to English speakers in one country, and just plain "wrong" to those in others. My personal bugbear is the common American English expression "I could care less". To a British English speaker this is just WRONG (we say "I couldn't care less").
